To @ZZ whom it may concorre:

siding at East Grange, in the county oi Essex and State of New Jersey, have invented certain new end use-tol improvements in Stoom- Traps, ofvvhich the following is a full, clear, and exact description, lsuch es will enable others skilled in the ort to which it opper- 'lhis inv/entier. reletes, broadly, to valves end to ,controlling Ineens for the seme, end more specifically to autometicelly-controlled velves and to steam-treps- @ne ot the objects thereof is to 1produce e device or the above type having e nigher deree ci general eiliciency than hss heretofore een attained.

Another Objectis to increase the dnrsibilu ity of such devices. 'l Y Another object is to provide e device of the nature of e steam-trap .which may be teken eport or adjusted. l

Another object is to provide e device of' the above general nature which will be certein end economical inaction and compnet in structure. Other objects will bein port obvious end in ert pointed out hereinafter.

'1. lie-invention accordingly consists in the features or construction, eornhinetione ot elements, and arrangement ofperts which will beexernplified in the herein-described e, peretus and the soep/e of the epplioetion el) which will be indieelted in the 'following claims.

The accompanying drei/ving is e sectioned elevation of one of various possible embodiments ci; my invention. y

As conducing to e better understanding oi certain features ofniy invention, it rney be here noted that in devices of the nature et steern-treps'ivlien,jthe dreinege-Weter ceases through the valve there is often e yconeidersole 'We-stev of li'vesteenirorn the system Withwliich the trap is conneeted;elso,' unless provision initie/de for such s contingency the partiel vriendin which is termed by the condensation ofthe stcern results in the vslv'e being prenisturely snapped into closed position. Moreover, ll have `found tiret unless the several' parte ore readily se arable end Lidjnsteble the meinte-7 nence oi? t e trop in e. satisfactorilyoperetive' condition is o constant source of core and my noyence. The above and other defects are remedied in construct-ions of the nature ot that hereinafter described.

Referring now to the illustrative einbodiment of my invention shown in the eccomponying drmving, l represents :i cross-valve' 6o inpipinrT 2, mounted upon the cor-body or other structure, the position of which is die.- gremrneticollv indicated et 3, this invention being particularly adapted for use in connection with the steam-heating system of reilwey-eers, although possessing marked velue in other relations. As valve L is of the ordinary constructionond es its specific details do not concern the present invention, it may be noted here merely that the seme com- 7'o prises e spindle 4 of such suitable length es to cerry the hond-wheel 5 into the desired position, this spindle essing through e suitehle stuffing-box 6 en: having mounted uponv i, its lower end the valve proper, 7, above en outlet 8. v 1 i Tapped into the valve i is si union 9, hev ing fixed therein e sieve or screen 10 for a. purpose hereinafter described. Upon'the other end ci union 9 is e threaded cas 1 11, prefer-- 8e ebly of substantially the forni iiliilioat'ed'end comprising, broadly, e body having dpi Worthy-projecting lugs, one of which is shown et I2, and s downwardly-extending outlet 1 i3. interlocking with this casing, es by Ineens of t tonGue 14 and socket 15, .is e oep 16, normally held in closed position-by means oi en eyebolt 17, pivotally mounted thereon between4 s pair of lugs, one of Which is indi* cated et i8. Topped upon this eyebolt is of 9o Wingnut 19, edo ted to rest between the lugs lf2 end secure y hold the con against the casing, elshoulder 2O being -formed upon the body thereof in order to eid in maintaining the ce in its ro er relative position. i

Nit in thepodly portion of the casing l1 is topped e bushing 21, forming n, seat for e vs lve 22. The letter member is pivotelly mounted upon e. pin 23, ellixed in s plone shove the valve to e pair of lugs, oneoi roo which is shown et 2e. The connection loetween volvo 22 endpin 23 comprises e hook 25 of such shone as readily to permit the volvo to swing With reference to the, casing end yet to prevent the seine becomingdeM m5 teched unless turned to o considerable angle with' reference thereto. When thrown into volatile iiuid 30. As the specific construction of this thermostat iorms'no part or' the present invention and it acts in a well-l nown manner to vary its external shape in accordance with the degree oi temperature to which the i'iu'idv therein is exposed, its form 'will not be desci-idoecl in detail.A ,l The lower end of the thermostat, it may be noted, projects within the path of drainage discharged through the valve 2 2, and thusds exposed to direct con.- tact therewith, thisy arrangement adding materially to the sensitive action of the tra it may also be noted that on account oftne in clined position oi the thermostat the chance of accumulation of drainage-water thereon, with a consequent decrease in efficiency, is avoided.

Thermostat 29 by means of the bosses 3l and 32, rests incontact with the valve 22 and an adjusting-screw 33, tappedthrough the outer Wall of the cap 16, as shown in the drawing, and preferably rovided with a lock-nut 34 in order to ren er its .action more certain.

It is an important feature of'this invention. that the valve, valve-seat, and thermostat are mounted in a position'inclined with respect to the vertical when in operative posim tion, as 4is indicated by the drawing. By

reference in the following claims to part as -inc'lined without further limitation is meant that thesanie is inclined with respect to the vertical when mounted in'its o erative position. Among the advantages o this inyc'linatifm of the parts is that the chance of y premature closing to the valve above reerred to is reduced to a minimum without sacrifice of otheradvantageous features. `In order to avoid any ambiguity as to the use oi certain terms employed throughout undergo a corresponding change in externalv sha e.- By operative portions, as used wit' reference to the valve or valve-seat, is intended lthose portions which are adapted tocontact the coacting member, and thus f' render the device operative.

" The method di use and operation oi` the above-described apparatus is substantially 'through the wi series as follows: ^assuming that the crosssvalvel is in operative relation to a steam-heating system mounted upon the structure 3, the steam having etree passage through the screen l() and the partially open valve 22 will fill the chamber formed by the casing 11 and ca 16 and rapidly heat the thermostat Q V ie latter device quickly'exp'anding in response to this increase ot' temperature forces the valve into a closed condition until` the water of condensation has accumulated above the same to such an extent as, by shielding the thermostat from the heat of the steam, to cause the same to contract, and

thus throw open the valve. The drainagewater then readily esca es through the valve, the maority of, t' e same passing ely-open lower portion of the passage, the escape of steam throughportion 35, when the leveloic the-waterchas 'f' fallen to such a oint as to leave a free aesage therethroug being rendered'insigniiicant in amount, since owing to the swinging action ot the depending valve 22 this 'opening is relatively small. 'When the lwater is entirely dischargedthe action ci the steam` on the thermostat 29 causes a of the valve, as above pointe out;

sufficient drainage-water has accumulated to fender such action desirable. vill-nen the connection with the streamheating system is broken, as by cutting7 out the car, the thermostat will become cooled and open the trap, thereby preventionr freezing of the water of cond ensation,

The function of the sieve orscreen l0, as

uick closing This cycle ol` operations is repeated .Whenever y i o'o should be apparent from the drawing, is to Aprevent the entry oi' foreign matter Within the tra i proper, with a consequent tendency vto cut t e facesof the valve or valve-seat or by lodgment between' the parts to interfere with the iine adjustment of thet-rap.

The hand-valve may he used'to blowout the drainage-water at wilimiithe-remote' event that the automatic tran becomes ino erative, and, if desired, the outlet of tie hand-valve may be formed so as to 'direct its discharge against the outer walls of the trap to thaw the same should the parts become 'frozen in osition.

it will t us be seen .tliat Ihaveprovided al devicewhich is we ll .adapted to accomplish the objects of my invention. The several parts are of thesimplest and most inexpensive construction, and the chances of the same becoming deranged in use are reduced ,Y

to a minimum. No spring,`with its consequent element oi uncertainty, is dependeitl upon to aid in opening or closing the valve, and the adjustment of both. tra and ther mostatjmay bte/.accomplished wit out'inconvenicnce or waste .of time. lThe several parts, moreover, are readily detachable, the'.

' tion which, as a matter of language,

wing-nut 19 and swinging the eyebolt from its position between lugs 12. s the ther mostat 29 merely rests uponthe ribs 28, `the same may then be taken from/its position in the cap without further manipulation of the parts and may be adjusted or replaced, as de- With the cap removed, moreover, the f sired. vvalve 22 may beuinstantly detached, being merely swung back lfrom the casing and unhooked from pin 25.

The entire structure is compact, simple,

and durable, possessing features which are of considerableindependent value in other relations and which when jointly embodied, as in the structure described, result in a trap which possesses many advantages, some Vof which have been suggested, some of which will be obvious, and others of which will become clear in the light of a full knowled e of the hard practical conditions to which t ese devices are subjected in use.

As many changesycould be made in theV above construction and many apparentlyv widely different embodiments of my invention could be f ade without departing from the scope thereof, I intend that all matter contained in the above description or shown in the accompanyingr drawings shall be interpreted as illustrative and not in a limiting sense. Y
